The probability of picking a martian that has completed 4 years of high school or is a male is 72 / 85.

Probability determines the odds that a random event would happen. The odds of the event happening lie between 0 and 1.

The probability = (total number of people who have finished 4 years of high school / total number of martains) + (total number of males / total number of martains)

58 / 170 + 86/170 = 144 / 170 = 72 / 85

Answer:  [tex]\frac{1}{16}[/tex]

Step-by-step explanation:

Whenever an exponent is negative, you flip the solution.

For this, [tex]2^4 = 2*2*2*2 = 4*4 = 16[/tex], however the exponent is negative, so flip 16 to get your final answer of [tex]\frac{1}{16}[/tex]

Answer:

Step-by-step explanation:

The given relations between numbers and prices can be used to write a system of equations for the number of each kind of ticket. One equation will describe ticket numbers; the other will describe ticket revenue.

Let x represent the number of adult tickets, and y the number of student tickets. The given relations can be written as the general-form equations ...

  8x -y -11 = 0 . . . . . . . . . ticket numbers

  5x +3y -895 = 0 . . . . . ticket revenue

The setup using general form equations lends itself to solution using the "cross multiplication method." Using this method, we define three numbers used in the solution:

  Δ = 8(3) -5(-1) = 24 +5 = 29

  Δx = -1(-895) -3(-11) = 895 +33 = 928

  Δy = -11(5) -(-895)(8) = -55 +7160 = 7105

And the solutions are ...

  x = Δx/Δ = 928/29 = 32

  y = Δy/Δ = 7105/29 = 245

32 adult tickets and 245 student tickets were sold.

Answer:

m∠R = 112°

m∠S = 112°

m∠T = 68°

Step-by-step explanation:

Quadrilateral QRST is a cyclic quadrilateral.

A cyclic quadrilateral is a quadrilateral drawn inside a circle where every vertex touches the circumference of the circle.  

The opposite angles in a cyclic quadrilateral sum to 180°.

⇒ m∠Q + m∠S = 180°

⇒ m∠R + m∠T = 180°

Given:

Measure of angle Q

⇒ m∠Q + m∠S = 180°

⇒ 68° + m∠S = 180°

⇒ m∠S = 180° - 68°

⇒ m∠S = 112°

Measure of angles R and T

⇒ m∠R + m∠T = 180°

⇒ (3x + 40)° + (5x - 52)° = 180°

⇒ )8x -12)° = 180°

⇒ 8x° = 192°

⇒ x = 24

Substituting the found value of x into the expressions for angles R and T:

⇒ m∠R = (3(24) + 40)°

⇒ m∠R = 112°

⇒ m∠T = (5x - 52)°

⇒ m∠T = 68°

Considering the given histogram, we have that:

1. Chebyshev's Theorem.

2. At least 89%.

3. At least 75%.

When we have no information about the population distribution, Chebyshev's Theorem is used. It states that:

An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].

We can see from the histogram that the distribution is not normal, hence Chebyshev's Theorem can be used.

-15 and 105 are within 3 standard deviations of the mean, hence the percentage is of at least 89%.

As stated in the bullet points, at least 75% of the measures are within 2 standard deviations of the mean.

Answer:

60 Days.

Step-by-step explanation:

Alright. We're told that the elementary menu repeats every 20 days. All right. And the middle school repeats every 15 days. And today they're both serving pizza. It asks how long until they're both saving it serving pizza again. Alright. So we can kind of just write them out and say well, if it's every 20 days, it repeats. Well then in 20 days from now we're going to get pizza again. And then after that another 20 days, so 40 days and then after that another 60 days. Okay. And we're just adding 20 each time. Uh you know, to see when would we get pizza again at the elementary school? Well, we can do the same thing here with middle school. And when are they going to get pizza again? Well, in 15 days from now they would get pizza again and then another 15 days from that. So that's 30 And then 45 and then 60 and then 75 and so on. And the first time that they're going to repeat is well, this is the common factor that are the common multiple that they have, which is 60. This is really just a complicated way of asking what is the least common multiple of 20 and 15. Alright. And your answer is going to be 60. So it'll be 60 days until they serve the same pizza again.

Step-by-step explanation:

For the first question,

3x + 4x + 2x = 180

9x = 180°

Dividing bothsides by 9

9x/9 = 180/9

x = 20

The measure of the interior angles are :

3x = 3(20) = 60

4x = 4( 20) = 80

2x = 2(20) = 40

For the second question,

Let's find x first.

x + 92 = 180

x = 180 - 92 = 88°

To find A note that:

A = 88° + 43°
